Revision of Experiments Tutorials and 'Theoretically Working' adaptations to OMF6

Christoph,

Experiment ruby files and tutorial files 1-3 are theoretically complete to use on the website. Filenames, experiment names, experiment output, etc has been modified to work with the changes I have made to the EDs.

Experiment tutorials 4-8 have the .draft extension as they are incomplete; I do not have enough knowledge and experience in OMF6 to accurately revise the existing tutorials myself. The experiment ruby files themselves however are theoretically working with the exception of the 'net' and '%' problems/non-implementations discussed earlier. The ruby code has simplified commented sections which should assist with future revisions.

I have also changed the filenames, eg 'TUTORIAL_01.mkd' to 'Experiment01.mkd' and 'tutorial01.rb' to 'experiment01.rb'. I guess this change will allow for better user readability.

Although the experiment tutorials and EDs will require significantly more changes as OMF evolves, these commits should serve as a solid base for these future revisions.
